Interface is the keyword here: interface != widget.

You build a widget with the interface you defined but the interface itself is not a widget.

Hey! I've found the solution myself again.)) I answered it at StackOverflow:
https://stackoverflow.com/questions/25340593/issue-with-fullscreen-mode-in-android-with-qt-5-3-1/59469941#59469941
Here is my result:

The status and navigation bars are hidden:

Hi
I dont know the answer but i was wondering if QWidgets or QML ?

Olá,
Está usando o QML?
Se sim dê uma olhada no tipo Drawer (https://doc.qt.io/qt-5/qml-qtquick-controls2-drawer.html).

Deve fazer o que deseja.

additionaly to what @raven-worx said, you can try setting this windowflag

setWindowFlag(Qt::MaximizeUsingFullscreenGeometryHint,true);

this should paint the window over everything.

Upgrading to 5.6 solved my issue.

@SGaist
Thanks Champ, I am checking it.

Thanks for the google map plugin, I study this post, the codes of your plugin and got some questions

1 : All of the information of google map are obtained by static api of google map?
2 : How could we support offline routing, offline search by term? By now all of the routing information are get from the server, to implement offline routing, we need to

a : download require map, data from the server
b : write our own algorithms to search the locations by terms and routing? I guess every maps data got their own format, but the locations searching and routing algorithms should be the same?

3 : QGeoTileFetcherGooglemaps is the main class of this plugin, which in charge of create request(by static api) and get the results back by the other classes?

Thanks a lot

@mrjj
Oh thank you very much. It's a good thing to learn!

Hi and welcome

While using QStackedWidget for all pages / screens could work just fine,
a more common design would/could be using
QDialog for welcome and login and when closed -
the main window for the graphs etc.

@VRonin Thanks!, this is what I ended up doing in the end, I just wondered if there was a nicer way like StackView.

This looks very promising, thanks ! :)

@p3c0 it does yet I wanted to fix the problem I personally faced thanks for an advice
